NVidia SolidWireFrame - directx

Question

I'm wanting to display some geometries using the solidwireframe, it appears to be a fx file with multiple effects and single passes.
So i wrote a class to perform what i thought the effect file was doing. The Header files are my Compiled Shaders, which are copies of the NVidia ones. compiled with version 4.0

now in my application, at the end of Initializing the Device and Context etc. i call.
SolidWireFrame* solidWireFrame = new SolidWireFrame();
solidWireFrame->Init(m_pd3dDevice.Get());
m_solidWireFrame.reset(solidWireFrame);
and my render loop.
//m_solidWireFrame->ApplyDepthAndSolid(m_pImmediateContext);
//m_solidWireFrame->ApplyDepthOnly(m_pImmediateContext);
//m_solidWireFrame->ApplySolidOnly(m_pImmediateContext);
/*for (it_drawingData iterator = dd.begin(); iterator != dd.end(); iterator++)
{

if (drawingData->IsRendered)

m_pImmediateContext->IASetIndexBuffer(drawingData->IndexBuffer, DXGI_FORMAT_R16_UINT, 0);
m_pImmediateContext->DrawIndexed(drawingData->IndexData.size(), 0, 0);
}
}
//not sure if i should call this between renders?
m_pdesignerSwapChain->Present(0, 0);*/
m_solidWireFrame->ApplySolidWirePattern(m_pImmediateContext);

}
}

Answer 1

Fixed it.
I was not setting the world, view, projection constant buffer for the wireframe vs.
